I can't imagine anyone that tried placing their phone with no case inside of this armband - it would be a joke!Just to give you an idea of all this extra space around the phone: if you plug in your headphones at the bottom of the phone through the armband, the phone gets pulled down outside of the little clear window, meaning that now a portion of your screen is below the clear window where you can no longer access it

They are relatively accurate in that they show that the S7 Edge fits right inside of the clear window - but what didn't occur to me is that there would be a lot of space all the way around the product allowing the phone to easily shift inside of the armband
